and manage your Z-Wave devices (lights, dimmers, blinds, you name it) from
within Node.js applications.  This library also supports secure
devices (e.g. door locks) that require encryption.  All widely used Node.js
versions are supported with the help of @code{node-nan}.

This library is currently able to:
@itemize @bullet
@item
scan a Z-Wave network and report on connected devices;
@item
write values to Z-Wave nodes;
@item
monitor the network for changes;
@item
heal nodes and/or the network; and
@item
perform management tasks: add or remove nodes, replace failed nodes,
manage their group associations, etc.
